'SWING-SASH LATCHIN G FIXTURE.

Application filed. August 15, 1924. Serial NO. 732,161

This invention has for its object to provide a device adapted for'attachment to hinge doors, windows and the like for firmly latchingthe same in closed or in open positions as desired without rattle resulting from gusts of wind when in said Open positions.

A further object of the invention is to provide a device of the character aforesaid which is small, compact, light, cheap and easy to manufactureand install and which is so constructed and arranged with respect to installation as to be capable of hearing all strains and stresses to which it is liable to be subjected without requiring that it be made of heavy materials and secured in place bv nunierous'or very long or large screws or the like.

The preferred embodiment of. the invention I is illustrated in the accompanying drawings wherein I Fig. 1 is a fragmentary elevation of a window-sash and its casing equipped with a .llXLlllG constructed in accordance With'the invention.

Fig. 2 is a plan section on the line 22 of Fig. 1. i

Figs. 3, i and 5 are perspective vlews of three component parts of the portion of the fixture adapted to be mounted on the window-casing or door frame.

The device is particularly adapted for hinged or so-called French windows which swingoutwardly from their frames and are, therefore, particularly subject to be ng buffeted by the wind. Numerous fixtures adapted for firmly holding windows of this type in desired open positions are'now on the market, the majority thereof being objectionable because they must be mounted on the window-sills in order to be accessible, or because they rattle under the influence of wind-pressures on the Windows When open, or for other reasons, including particularly the objection of high cost and difficult installation. i I

The device of this invention is designedto overcome all of the objections which have mitigated against the use of fixturesintended for the same general purposes,primarily by (a) enabling it to be installed at the top of the window and its casing whileoperable from an easily accessible elevation; I (Z2) rendering it very compact and capable of being easily installed by unskilied persons; (0

obviating possibility of rattle, and generally render ng the same pract cal for use.

The (lGVZLGH comprises a Wall-plate '1 hav- ,ing a relatively long flat upper flange 2 and a shorter fla tflower flangeg, the plate 1 being adapted to be secured to a side of the window-casing or door-frame adjacent the top thereof. In Said fianges2 and 3 there are provided two vertically aligned, transverse slots 4 and 5, respectively, the former bei of greater length than the latter.

Associated with said flanges 2 and 3 is a plate 6 having an offset end-portion 7 and a flange 8, the latter termi'natlng in a tongue -9 and projection 10. The tongue 9 is adapt ed to be received in and snugly. fit the slot 4: .and the projection 10 to pass through and snugly fit the slot 5, the length of the tongue 9 being exactly equal to the distance separat mg the upper-surfaces of the flanges-2 and 3 so that the shoulders 11 and 12 will rest upon said flanges 2 and 3 when the projection 10 is passed through the slot 5] The said projection 10 isof greaterlength. than the thickness of the fian e 3 so that it will proectbelow the same, the projecting end portion being upset like a rivet (as indicated by reference character 11) to permanently secure the plate 6 to said flanges 2 and 3.

When thus secured, the plate 6 will be spaced from and extend parallel with the flange 2 and project bcyondthe outeruend of thelatter, the offset end-portion 7 thereof being provided with a perforation .12? to re-.

with a. perforation 13 which is disposed in vertical al gnment with a simllar perforation 14 in the outer end portion of 'the'fiange 2.

said perforations 1-3 and 14 being adapted to receive the pivot-element 15 for the flat circular plate 16 provided with the integral radial arm 17, said plate having a series of perforations 18 arranged at regular inter- -vals equidistantly from the axis of the per foration 19 in the center thereof through whichthe pivot element 15 (preferably rivet) passes. One of said perforations 18 is disposed diametricaily opposite the arm 17 I and the remaining perforations '18 arefdisposed inequal number to the right and left 7 thereof so that, in assembling the fixture it having perforations'for the passage of fas tening screws 28, in one arm and a slot of somewhat greater length than the width of the arm 17 of plate 6 in the outer end por will be capable of installation at either the right or left side of the window casing or door-frame.

- In the flange 2, between the slot 4; and opening 14t,' there is a perforation 20 and in the outer end of the flange 3, a perforation 21 vertically aligned with the perforation 20.

A latch bolt 22 having a slightly tapered upper end-portion to engage in the perforations 18, is mounted for reciprocation in said perforations 20 and 21. Said latch-bolt 22 is provided adjacent its upper end with a cross-head or similar stop formation for limiting its upward movement and for engaging the upper end of the helical compresslon spring 24 which surrounds said latch bolt and bears at its lower end upon the flange 3 to thus hold said latch-boltnormally at'the upper limit of itsmovement. The diameter of the perforations 18is slightly less than i perforation 12 cooperates W1 th the fastening that of the body of thelatch-bolt 22so that the tapered upper end of the latter will snugly engage therein before the, said latchbolt has attainedthe upper limit of its movement' as determined by the cross-head 23.

Preferably, the plate 6 is provided with a perforation 25 vertically aligned with the perforations 20 and 21 and of larger diam- .eter than the extreme upper end ofthe latch bolt so that the latter may project above the plate 16 and into said perforation 25. Secured to the lower end of the latch-bolt 22 'is. a pull chain 26 for operatingthe same against the action" of said spring 24, the

length ofthe latter, when completely collatch-bolt'to a point at which its extreme upper. end is disposed below the plate 16 but above the lower face of the flange 2. The depth of the flange 8 of the plate 6 is such as to space the latter from the flange 2 a distance only slightlygreater than the thicknessof the plate 6. I

Mounted on the upper rail of the window or-door-sash is an'L-shaped guide plate 27 tion of its other arm. The position of said slot'29 is such that its outer'end wall contacts with the outer edge of the arm 17 when,

the latter is disposed parallel with the sash and is spaced from the latter a distance slightly in excess of the length of the radius of the plate 16. A flat spring 30 having perforations adapted for alignment with; those of: the L-shaped guide-plate 27 through which the screws 28 pass and'having an ogee cu'rved'end portion 31 bearing at its free end portion on the inner edge of the arm 17 -adjacent its point of engagement in the slot 29, is secured in placeby the said screws 28.

The operation of the device will bereadily as to permit the sash to be opened to the fullest extent (through an arc of a little more-than ninety degrees) without eifecting withdrawal of the arm 17 from the slot 29.

It is therefore disposed a predetermined distance from the side wall ofthe casing to which the plate 1 is attached and its eleva tion determined by the position of the latter on said casing.

The elevation of the plate 1 is determined by the offset end-portion 7 of the plate 6. The spacing of the plate 1 V from the inner face of the sash is determined by the uide-plate 27. The person installing the fixture is thus easily guided and instructed in effecting such installation: 4 y

The fastening screw passing throughv the screws for the plate 1 to readily transmit all stresses and strains on the fixture to the wincorner of the casing, is usually hidden from view by draperies. It presents no disadvantages either from the standpoint of cutting off light, window sill area, interference with draping, difliculty of installation or opera tion or rattling, the spring 30 and snugyflts of operating elements obviating lost motions usually responsible for such rattling.

Obviously, the device is adapted only for outwardly swinging windowsand doors and 'is adapted for the type of window which swings on a horizontal axis] similarly to transoms. I :ong lifeis further assuredby having the pivot element 15 rigidly supported at both ends to thus relieve it of tortional strains and stresses tending to loosen it.
